The impact of low-dose contrast agents on the image quality of one-stop CT scans in patients with chest pain triad
低剂量对比剂对胸痛三联征患者一站式CT扫描图像质量的影响

摘要

目的 分析胸痛三联征患者使用一站式CT扫描时使用低剂量对比剂对其图像质量的影响。方法 纳入2022年7月~2023年7月内我院收治的60例胸痛三联征患者为研究对象，患者均行一站式CT扫描，按照随机对照方式分为对照组（常规剂量对比剂）和观察组（低剂量对比剂）各30例，对比两组扫描情况。结果 两组患者冠状动脉和肺动脉成像质量差异及诊断情况差异均无统计学意义（P＞0.05），但观察组扫描过程对比剂肾病的发生率显著低于对照组，差异存在统计学意义（P＜0.05）。结论 临床中对胸痛三联征患者行一站式CT扫描时使用低剂量对比剂对其图像质量具有较好成像维持效果，提高诊断结果准确度，为临床治疗提供参考，同时减少对比剂肾病的发生，安全性较高。

Abstract

Objective To analyze the impact of low-dose contrast agents on the image quality of patients with chest pain triad during one-stop CT scanning.
Methods Sixty patients with chest pain triad admitted to our hospital from July 2022 to July 2023 were included as the research subjects. All patients underwent one-stop CT scans and were randomly divided into a control group (conventional dose contrast agent) and an observation group (low-dose contrast agent), with 30 patients in each group. The scanning results of the two groups were compared.
Results There was no statistically significant difference in the imaging quality and diagnostic status of coronary and pulmonary arteries between the two groups of patients (P>0.05), but the incidence of contrast agent nephropathy during the scanning process in the observation group was significantly lower than that in the control group, and the difference was statistically significant (P<0.05).
Conclusion   In clinical practice, the use of low-dose contrast agents during one-stop CT scanning for patients with chest pain triad has a good image quality maintenance effect, improves diagnostic accuracy, provides reference for clinical treatment, and reduces the occurrence of contrast agent nephropathy, with high safety.
